I FLOUR-MILL- c EARING ATTACHMENT.

SPECIFICATION forming-part of Letters patent No. 734,880, dated July as, 1903.

' A lication filed Octoher 27, isoaj' fierial 110128.980. (NomodeL) T aZZ whom it mag concern:

Be it known that we, NIELs H. JORGENSEN and HARRY R. PALMER, citizens of the United States, residing at Sleepyeye, in the county of; Brown and State of Minnesota, have invented" a new and useful Flour-Mill GearingAttachment, of which the following is a specification.

Our invention is an improvement in gearing attachments for flour-packers; and the ohjeot is to provide a gear which will obviate the liability of clippings from the bevels falling into the flour being packed.

In packers now extensively in use the bevels are located directly above the sackor bar- 'rel being packed, and as themachine does not run continuously, but is stopped after the filling of each sack or barrel, the frequent engagement and disengagement of the gears cause them to wear rapidly, the metal parti- We overcome this.

cles getting into the flour. difficulty by keeping the gear in position at all times, cutting the counter-shaft, andiinsorting therein a spiral gear, which is fully illustrated in the accompanyingdrawings, in whichx Figure 1 is an elevation of the upperpor- .tion of the flour-packing m'achine,showing. our improved clutch imposition; Fig.1 is a, detail view illustrating the connection of the" chain to the operating-lever. Fig. 2 is an enlarged detail plan view showing the clutches open, and Fig. 3 is a detail sectional View on or about the line 3 3 of Fig. 2.

In the drawings, A represents the upper part of the frame of a packer, A a part of the packing-case, and A the gears adapted to rotate the shaft A These parts are common to the packers now in use.

imparted to the gears A G O are post-boxes in which the counter- B is the counter-shaft by which motion is' shaft is 'j ournaled. Spiral clutch members D',

D are secured to the cut ends of thecoun'tershaft,respectively,being prevented from to rning on the shaft by set-screws D Between collars E E a block F is loosely mounted, a bracket F preventing the block from turning, the bracket fittinginto a groove F formed in the block.

A spring G is secured to the lug F formed .On a bracket F carried on the upper part of frame A. A pin 1 fits through an aperture 1 iuthe lever and engages recesses 1 produced in the frame A. It is readily seen that as soon as the lever is released by withdrawal of the pin the spring G will automatically draw the clutch D from engagement with the clutch D, and by drawing the lever down. the clutches are engaged and the gears started without the jar produced by the positive ongagement of'a revolving gear with a stationary one.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is-

l. The combination with a cut counter- .shaft, of. spiral clutch members arranged on the adjacent ends of said shaft, a block loosely mounted on said shaft, means for preventing lateral or revoluble motion of the block, a spring adapted to withdrawthe clutch members'fromfengagement one end of said spring being secured to the block, a chain attached at one end to the block, a lever to which the opposite end of the chain is attached, and

means for locking the lever in a lowered position. V

2. The combination with spiral clutch members carried by acut counter-shaft, of a block loosely mounted on the shaft, said block beirm}; recessed on one side, a bracket secured adjacent the shaft and adapted to extend into said recess and prevent the block from turning,-perforated' ears formed on opposite sides of the block,'a spring secured to one of said ears, and a chain secured to the other, and means for preventing lateral movement of the block.
